Text Encryptor
Encrypt/decrypt text with AES-GCM (passphrase-derived key) or RSA-OAEP (key pair). Everything runs locally in your browser.
About this tool
AES Encryptor is a free online tool. Encrypt and decrypt text or files with AES.
Enter plaintext and key, select the AES key length (128/192/256 bits) and operation mode (CBC, TLR, GCM, etc.). The tool generates encrypted ciphertext (Base 64 or Hex format) and initialization carrier (IV). Enter ciphertext, key and IV to recover when decrypting.
Encryption uses the SubtleCrypto interface of the Web Crypto API, which is an encryption API provided locally by the browser and has performance close to that of local code. The AES-GCM pattern provides encryption and authentication (tamper-proof) and is recommended for most scenarios. This key can be obtained through a password (PBKDF2) or entered directly.
Suitable for encrypting sensitive data such as passwords and keys before transmission or storage. Please note that key management is important. If you lose the key, you will not be able to decrypt it.
AES encryption and decryption tool uses AES-128/192/256 algorithm to encrypt text or files, and supports CBC, TLR, GCM and other modes.
